SECTIONAL CONGRETE ASH REOEPTACLE'.

Application filed October 3.0, 19.25..

The present invention relates to a knock down ash receptacle.

l/Vhere coal is used as. a fuel in heating residences and the like, the disposal of the ashes therefrom is sometimes an annoying problem, since if thrown out into the; yard or alley o f the residence they are unsightly and may be tracked into the house by persons: walking across them;

An object of the present invention is to make a plurality of sections which may be assembled without the use of tools or cement to form a receptacle for the reception and storage of ashes.

Another object is to form curved slabs of concrete with interlockings joints which may be assembled in interlocking relation without the use of tools or cement to form a domed receptacle, one of said sections having an extension therefrom to form a support for a garbage can.

In order to attain these objects. there 15 provided, in accordance with one feature of the invention, a plurality of concrete slabs,

' each of which is provided with a tongue on one vertical edge and one horizontal edge, and with a groove on the other vertical edge and on the other horizontal edge. The slabs are curved laterally and taper inwardly toward the upper edges thereof, so that when the slabs are assembled they form a plurality of superposed circular sections, each section being of smaller diameter than the one below it, so as to form an inwardly tapering receptacle. A single annular member is provided to fit over the top edge of the upper section and to interlock therewith, the annular member having an opening centrally thereof. A removable closure member is provided for said central opening. In the bottom course one of the slabs is provided with a lateral extension of a size to support a garbage can, and this support also acts as a step upon which one may stand while pouring ashes into the receptacle.

These and other features of the invention not specifically mentioned, will be more fully brought out in the following description and the accompanying drawings, wherein:

Figure 1, is a view partly in elevation and partly in section of a device made in accordance with the present invention.

Figure 2, is a sectional view on the line 2--2 of Figure l; and

Figure 3, is a view in perspective of a portion of three of the concrete slabs of which Serial No. 65,827.

the device is constructed, in position for l assembling. 7

Referring to:- the drawings in detail, re-

' ceptacle A is assembled from. a plurality of concrete slabs l which are formed of varying on. both. the top and bottom thereof for the bottom; course, and. have a lateral curvature at their bottom edges on an of the circumference of the base of the receptacle. The slabs are tapered toward their tops and are curved at their upper edges on an arc of a circle having a diameter slightly smaller than that of the base. Each superposed sec tion is formed to rest on the next lower section and to have its upper edge of smaller diameter than its base. A separate mold is required for the slabs of each superposed section, all of the slabs of each sdhtion' being identical with the exception of two slabs 3 and 4: adjacent a cleanout door 5 in the lower course. These two slabs are each provided with a guideway 6 which may be composed of sheet metal, and embedded in the slab, shaped as illustrated, to form a slide for the door 5. The door comprises a sheet of heavy metal with a handle 6 formed of the outward and downwardly turned upper edge thereof.

An annular member 7 of 'T-iron is provided, upon which the base course is assembled. The annular member 7 is laid on the spot upon which the receptacle is to be erected with the stem of the T upward. The member 7 is of a diameter which will properly position the slabs for the assembly of the subsequent courses when said lower slabs are erected with their grooved lower edges containing the stem portion of member 7. A reinforcing hoop 8 of heavy iron wire may be inserted in the groove in the top of each section before assembling the next higher section theron, the tongues on the lower edges of the blocks being sufliciently smaller than said grooves to clear said wire members when placed therein. These wire hoops greatly strengthen the structure against internal stresses, but are not essential since the weight of the ashes contained in the device is never suflicient to cause outward displacement of the slabs.

The upper edges of the slabs of the upper section are made flush, and an annular top member B, constructed of reinforced concrete, is provided with a groove 9 in the lower face thereof to receive the upper edges of the slabs of the upper section therein, thus firmly interlocking said slabs and forming a closure member across the top of the receptacle. An opening 10 is provided centrally of the annular top member, and within said opening is afiixed a metallic thimble ll which fits closely into the opening and is held in position therein by means of reinforcing members 12 embedded in the concrete of which the top member is preferably formed. A sheet metal cover 13 is of a size to readily tit within the thimble and is provided with a handle l t on the top thereof for manipulating the cover.

Extending laterally outward from one of the bottom slabs, and integral therewith, is a support 15 of a size to support a garbage can 16 thereon.

What I claim is:

A receptacle of the character described, comprising a plurality of curved interlocking sections positioned in annular layers superposed one upon another, one 01 said sections having a protuberance thereon to form a shelf extending outwardly from the side of said receptacle, each of said sections having a groove in the upper edge thereof, and a tongue in the lower edge thereof to fit into thegroove in the next lower row of interlocking sections and to terminate short of the bottom thereof, and an annular metal reinforcing ring insertible in the groove in the upper edges of each row of sections to bind said sections against outward displacement.

In testimony whereof I aflix my signature.
